Default Newbie to pulse induction detecting

I'm not new to metal detecting but I've never used a pulse induction detector. I bought a Golden Mask Mobile ST which will arrive tomorrow. I bought it to look for military relics at a decommissioned army base where I know for certain there are things like collar disks, medals and hat pins that can be at least as deep as two feet and maybe more - including spot dumps where they dug a hole and threw in buttons or marksmanship badges or medals.

My first question, without ever having used a PI detector, is about coil sizes. I will have three different sized coils: 7, 11 and 16 inch. Does a PI detector see deeper with the same size coil than a VLF detector on something like a brass collar disk or a silver quarter? Or does it face the same basic depth limitations as the VLF machines based on coil size? The soil will be somewhat mineralized due to the amount of rust iron nails of different sizes.

I'm sure that I'll have more questions later but that is my first for now. Thank you for your help.
